Description

Technical Field

[0001] This document relates generally to wireless communications, in particular fifth generation 5G wireless communications, such as 5G New Radio (5GNR), and more specifically to QoE measurement. Background Art

[0002] Understanding the end-to-end customer experience (e.g., throughput, data loss, latency) has attracted the attention of network operators. Quality of Experience (QoE) measurements can be defined based on different applications and measurements occurring at the application layer of the UE, including measurements of throughput, data loss, latency, etc.

[0003] NR (New Radio) QMC (QoE Measurement Collection) functionality is activated by OAM (Operation, Administration and Maintenance) via a separate QMC framework. For signaling-based QoE, the QMC configuration for a specific UE is sent from OAM to the CN (Core Network), which then sends the QMC configuration to the Radio Access Node (RAN) node via UE-associated signaling. For management-based QoE, OAM sends the QMC configuration to the RAN node, and the RAN selects a UE that meets the conditions for QoE measurement and sends the configuration to the UE.

[0004] RAN visible QoE is a sub-feature of QoE. When QoE has been activated, RAN can configure RAN visible QoE based on its own requirements. RAN visible QoE should be associated with QoE through the measurement id of QoE. UE collects RAN visible QoE measurement results and reports them to the RAN node. The RAN node will use the measurement results for network optimization. In the central unit-distributed unit (CU-DU) split architecture, the CU should transmit the RAN visible QoE measurement results to the DU via F1AP. In addition, QoE measurement needs to be further enhanced. Summary of the invention

[0170] Example 1 (QoE UE capability parameters for AR, MR, MBS and other service types)

[0171] Figure 1 A schematic diagram is shown of transmission / reception of QoE UE capability parameters for AR (Augmented Reality), MR (Mixed Reality), MBS (Multicast and Broadcast Service) and other service types according to an embodiment.

[0172] Considering some new service types supported in QoE measurement, it is necessary to carry these new service types when the core network and gNB are instructed to perform QoE measurement. For example, the QMC configuration information of the core network and the RRC reconfiguration of the gNB contain service types for AR, MR, and MBS. In addition, similar to streaming media and MTSI services (Multimedia Telephone Service) that already support QoE measurement, new service types that need to be supported are reported in the UE's capability information. That is, the QoE parameters of the UE capability information include whether QoE measurement of AR, MR, and MBS is supported.

[0173] Example 2 (QoE UE capability parameters in non-connected state)

[0174] Figure 2 A schematic diagram showing transmission / reception of QoE UE capability parameters in a non-connected state according to an embodiment.

[0175] Considering that QoE supports MBS measurement in RRC inactive (RRC_INACTIVE) and RRC idle (RRC_IDLE) states, this means that before the core network, it is necessary to know whether the current UE supports non-connected state QoE measurement, and the gNB distributes the QoE measurement configuration. The UE capability information includes an indication of whether QoE measurement is supported. The indication includes at least one of the following items: only RRC_INACTIVE measurement is supported, only RRC_IDLE measurement is supported, non-connected measurement is supported, and RRC_INACTIVE and RRC_IDLE measurement are supported.

[0178] Measurement configuration

[0179] In Rel 18, in order to support QoE measurement in a non-connected state, the gNB needs to configure the QoE measurement information used in the non-connected state for the UE in the connected state. According to the embodiment, the configuration of the above information is as follows:

[0180] - Option 1: By default, or by indications defined in RRC reconfiguration (RRCReconfiguration) and RRC resumption (RRCResume), it is indicated that the currently configured QoE configuration information also applies to the non-connected state.

[0181] - Option 2: In RRC release (RRCRelease), while releasing the QoE measurement information configured by the connected state, the gNB configures the QoE measurement information in the non-connected state.

[0182] - Option 3: In RRCRelease, while releasing the QoE measurement information configured by the connected state, the gNB adds and modifies the current QoE measurement to the non-connected state.

[0183] The QoE configuration information is the application layer measurement configuration (AppLayerMeasConfig), which includes at least one of the following items: measurement configuration application layer will add modification list, measurement configuration application layer will release list, allowed RRC segmentation, measurement configuration application layer Id, measurement configuration application layer container, service type, pause reporting, session start and stop transmission, slice list, short IP information, period, number of buffer level entries, and report playback delay for media startup.

[0184] These parameters are further specified in the Appendix.

[0185] Measurement reporting

[0186] In the non-connected state, the processing of QoE measurement reporting for a service (e.g., MBS) includes at least one of the following methods:

[0187] - Option 1: When the UE enters the connected state, the UE reports the QoE measurements stored in the UE.

[0188] - Option 2: In the non-connected state, the UE reports QoE measurement information based on a periodic or event-triggered basis.

[0189] - Option 3: In the non-connected state, the UE triggers a state switch to connected based on the QoE measurement information.

[0190] In option 2, in the non-connected state, the UE sends QoE measurement information to the gNB through small data transmission (SDT). The QoE measurement information includes at least one of the following items: traditional QoE measurement report, RVQoE measurement report, QoE measurement report level value, RVQoE value, UE application layer indication indicating the effect of user experience, slice information, QoE measurement ID, and RAN visible QoE measurement ID.

[0191] The above information should be sent through at least one of the following methods:

[0193] - Event triggering, where the triggering condition includes at least one of the following items: indication information from the UE application layer, the QoE measurement reporting level exceeds a threshold, the RVQoE value exceeds a threshold, and / or one or more indicators in the QoE measurement report exceeds a corresponding threshold.

[0194] The above thresholds are carried by the core network or gNB when configuring QoE measurement parameters.

[0195] The carrying method includes one of the following items: the threshold is included in the QoE configuration container, and / or the threshold is included in the RRC signaling.

[0196] In option 3, in the non-connected state, the UE triggers switching to the connected state based on the QoE measurement information.

[0202] In addition, after entering the connected state, the gNB requests the UE to report QoE measurement reports based on the above indication information.

[0203] Embodiment 4 (MN or SN sends QoE measurement report to UE)

[0204] Figure 4A A schematic diagram of QoE measurement reporting according to an embodiment is shown.

[0205] In the current standard, the MCG SRB in the DC scenario supports SRB1 and SRB2 transmission, and the SCG SRB supports SRB3 transmission. In the single connection scenario, due to the low priority based on the QoE report, the QoE report separately introduces a low-priority SRB4 to send the above measurement report. Therefore, the MN needs to support the above measurement report sent by SRB4. For the SN, since SRB3 supports reporting measurement reports, SRB3, split SRB4 or new SRB5 can be used to send QoE measurement reports. For the UE, the UE indicates whether the UE supports RRC segmentation of the measurement report message in the uplink. The above measurement report includes both RAN-visible QoE reports and traditional QoE reports. In the case of NR-DC, the UE measurement reporting method includes at least one of the following items:

[0206] The MN or SN configures the QoE measurement information, and the UE always sends measurement reports to the MN, such as Figure 4A As shown in FIG. 4 , the QoE measurement report is reported to the MN via SRB4.

[0207] Figure 4B A schematic diagram of QoE measurement reporting according to an embodiment is shown.

[0208] The MN or SN configures the QoE measurement information, and the UE always sends measurement reports to the SN, such as Figure 4B The QoE measurement report is reported to the SN via SRB3, split SRB4 or new SRB5.

[0209] Figure 4C A schematic diagram of QoE measurement reporting according to an embodiment is shown.

[0210] The MN or SN configures the QoE measurement information, and the UE sends the measurement report to the MN by default. The MN or SN can instruct the UE to report the measurement report to the SN through the indication information, such as Figure 4CAs shown. The QoE measurement report is reported to the MN through SRB4, and the QoE measurement report is also reported to the SN through SRB3, split SRB4 or new SRB5. DL information includes at least one of the following items: DLInformationTransfer, RRC message, MAC CE (including indication information), and DCI (including indication information). RRC message includes at least one of the following items: RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, RRCSetup.

[0216] Figure 5 A schematic diagram showing alignment of QoE measurements according to an embodiment is shown.

[0217] When both the traditional QoE / RAN visible QoE measurement and the MDT measurement are activated, the two measurement results need to be associated to assist the core network or gNB in ​​the joint analysis of the QoE measurement results and the MDT measurement results. In other words, the two measurement results are associated with the auxiliary information in the measurement reports of the traditional QoE and RAN visible QoE. The auxiliary information includes at least one of the following information: absolute timestamp, relative timestamp, slice information, QoE measurement ID, RAN visible QoE measurement ID.
